摘要
岩溶管道水汇流是一种特殊的非稳定流,根据其单位水头流速(?)和水力比降I的相关曲线分析,建立相应的数学模型,为探索岩溶管道水运动问题,提出了新的理论和研究方法。
Experience has shown that Darcy's law cannot be applied to karst areas, especially to pipe- flow which exists mainly in karst areas. Because it is characteristized by rapid flow. large discharge, gentle gradient and low potential energy of ground water level, so karst pipe- flow can pirate waters from minute pipes or solution fissures and eventually form gathered movement. of ground water which can be defined as confluence terminologically. The confluence is a particular unsteady flow.
One of the important techniques of confluence study is karst water racing. The essential factors in the study are flow velocity of unit head of azter ui and gradient ratio I. Its fundamental theory is regression analysis. The study of confluence provides a new theory and method for investigating karst pipe water problems.
